化学是一门以实验为基础的自然科学 ,多年的教学实践证明 :化学实验不仅是学生获取化学知识、认识化学规律、形成化学概念、提高各种能力的重要途径 ,而且此过程对学生的创新精神和创新能力的培养 ,是其他学科所不能替代的。因此 ,我们必须立足化学实验这个基础 ,努力构建培养 Chemistry is a natural science based on experimentation. Many years of teaching practice has proved that chemical experiments are not only important ways for students to acquire chemical knowledge, understand chemical laws, form chemical concepts, and improve various abilities, but also the innovation of this process for students. The cultivation of spirit and innovation ability cannot be replaced by other disciplines. Therefore, we must base ourselves on chemical experiments and strive to build
